Modal toolbar icon style missing

I’ve got modal, where, instead of writing “Close” on the left part of the toolbar, I want to display only an icon. I followed the ionic-conference-app template ( and just replace the text with an ion-icon like following:

        <ion-buttons start no-shadow>
            <button ion-button (click)="close()">
                <ion-icon name="close"></ion-icon>


This works fine except that I noticed that the icon doesn’t inherit the padding and font-size attributes like a menuToggle. Meaning these css attributes are missing (in case iOS) and the icon doesn’t look great (no padding, too small):

.bar-button-menutoggle-ios ion-icon {
    padding: 0 6px;
    font-size: 2.8rem;


Do I miss an attribute to add to my button?
